This is an Arca-Swiss Monoball p0 with Quick Set Device “Monoball Fix” The camera can be moved in an ergonomically precise way with one hand, while the other opens and closes the ring which goes round the ball of the ball head. The unconventional position of the pan arm (on the ball) always guarantees that the vertical is maintained when panning.
The tripod heads of the p0 series are the best value for money tripod heads made by Arca-Swiss. With their “record light weight” of approximately 350g they make themselves the ideal tripod head to travel with. The ball has a range of swivel of 90° and a pan angle of 360°. Despite its light weight and small dimensions it has a durability that cannot be matched. Load Capacity is 20kg.
